These are the permanent residents of Sonmarg though seasonally.

Sonmarg had historical significance and was a gateway on ancient Silk Road[3][4] along with Gilgit connecting Kashmir with Tibet. The Zoji La pass lies 15 km east and is one of the highest passes for road transport. It still is a base camp for Ladakh on NH 1D, and is strategically important for Indian army for the defence of Ladakh.

In late April when Sonmarg is open for road transport, the visitors can have access to snow which is furnished all over like a white carpet. Private vehicles are not allowed. Visitors have to hire taxi and it is controlled by taxi mafia. Ponies can be hired for the trip up to Thajiwas glacier a major attraction during the summer months.

Sonmarg is easily accessible from Srinagar or Srinagar Airport (SXR), the capital of Kashmir, in under 3 hours by car or by bus on NH 1D 87 kilometers which leads along Nallah Sindh a key tourist attraction. Sonmarg is inaccessible during winter due to heavy snowfall and avalanches, NH 1D is closed in December every year, the local traffic is permitted only up to Gagangear village, which is the last permanent settlement of this area. Only the Choppers of Indian army lands at Sonmarg[10] during winter carrying essentials for the army camp, and the army personnels are the only people who stay at Sonmarg during these harsh weather conditions. After Kargil war these high altitude meadows have seen heavy deployment of Indian army.[11] The government has given a green signal to dig a 6.5 km long road tunnel, Z-Morh Tunnel, at Gagangear and 14.2 km long tunnel at Zoji La, which will not only keep Sonmarg open round the year but also the road to Dras, Kargil and Leh in Ladakh. This project is still on paper and the construction has not started.[12]

Main attraction of this place is Thajiwas Glacier. Be very careful from the pony and car touts. This will always misguide you and ask handsome amount to access them. Your normal car will not have access to reach Thajiwas Glacier. You must need to hire either pony or four-wheel drive SUV to reach there. It is just about 5 minute drive by car. They may be ask you about Rs.900 for pony per person or Rs.5,000 per vehicle. Always negotiate with them. You can easily negotiate them for Rs.700 for three places (Thijiwas Glacier, Fish Pond & Sarbal Park). In Thajiwas, you will get the snow but tout will misguide you for not having over there. At last if you want to enjoy snow in Thajiwas Glacier, hire a SUV vehicle for Rs.2,000, I'm sure you will see it (snow) over there.

You can hire sledge-cart for Rs.100 to 200 and gum boots for Rs.50 to 100 in May (which is peak time for them).
